摘　　要：利用2015年10月—2016年9月青岛市4个区PM_(10)、O_(3)、PM_(2.5)、SO_(2)、NO_(2)、CO 6种污染物、气象数据和车流量数据,统计分析了6种污染物的时空分布特征及污染物平均浓度与气象要素的相关性,并分析了污染物浓度与车流量之间的关系。结果表明:青岛市空气污染物具有明显的季节性差异,SO_(2)、NO_(2)、CO、PM_(10)和PM_(2.5)的浓度呈现夏、秋季低,冬、春季高的特点;O_(3)浓度呈现春、夏季高,秋、冬季低的特点;PM_(2.5)和PM_(10)在春季的浓度比夏季高;除O_(3)外,污染物浓度与降水量和气温呈负相关,与气压呈正相关。污染物浓度与车流量没有显著的相关关系。In this paper,the meteorological data,traffic flow data,and PM_(10),O_3,PM_(2.5),SO_2,NO_(2) and CO in four districts of Qingdao from October 2015 to September 2016 are used,the temporal and spatial distribution characteristics of six pollutants and the correlation between the average concentration of pollutants and meteorological elements are statistically analyzed,and the relationship between the concentration of pollutants and traffic flow is analyzed.The results show that there are obvious seasonal differences in air pollutants in Qingdao.The concentrations of SO_2,NO_2,CO,PM_(10) and PM_(2.5) are low in summer and autumn and high in winter and spring;O_(3) concentration is high in spring and summer and low in autumn and winter;The concentrations of PM_(2.5) and PM_(10) in spring were higher than those in summer;Except O_3,the pollutant concentration is negatively correlated to precipitation and air temperature,and positively correlated to air pressure.There is no significant correlation between pollutant concentration and traffic flow.
